Resumo
The viability of small-scale heavy-metal waste immobilization into iron phosphate glasses was investigated. Several waste forms
containing different amounts of heavy-ion wastes were evaluated (5%, 10%, 15%, 20%, 26%, 33%, 40% and 50% by mass) and their
X-ray diffraction patterns revealed that no crystallization occurred in glasses with waste concentrations up to 26%. The dissolution
rates for all of the reported glass compositions (ca. 10–8 g cm–2 min–1) are similar to those reported for the materials most commonly
used for waste vitrification. Iron phosphate glasses thus proved to be very useful for the immobilization of heavy-metal wastes,
exhibiting good contention and chemical durability comparable to that of borosilicate glasses.
